This is the **sixth handoff of the existing490d Unified Chronology research**, continuing through **C479**, not a restart.

Read **`490d_Sixth_Handoff_C479_20260925.md` first**, then the new reading guide, archive verification, direction/correction ledger and C01–C479 report/evidence locator. Use **`490d_C479_Sixth_Handoff_Compact_Restart_Kit_20260925.zip` as the active working packet**. Treat **`490d_C01_C479_Complete_Window_Archive_20260925.zip`** and its intact nested older archives as reference libraries; inspect indexes and retrieve dependencies selectively. Current corrections and scope decisions override stale archived instructions and old next-step paragraphs.

Verify actual access to File_18,File_09 and the C479 checkpoint, with C265 continuity preserved. Verify report/evidence availability through the supplied locators and integrity records without reading every historical report. C01–C479 are distinct from original unprefixedReports01–10, the unestablished interrupted originalReports11–25, and the comparative Engine reports. The September17 original is now intact and hash-verified; its old partial-copy warning is superseded.

Keep the **Mirror and529 focus**; regular Gears remain **Noah/Shem/Flood only**. The original proposedC266 AD1905–1911 check was superseded; actualC266 began the important529 update. Preserve both supplemental LXX8464 corrections and the SKL appendix without redirecting research.

**C480 has not been done:** it proposes reducing the existing51-coordinate/101-label1150 interval inventory to disjoint source-role/context templates and explaining the three admitted fixed-E expansions. Do not add dates,pivots,phases or operators.

First return a concise access/status summary and a small restart checkpoint, then wait for my instruction before new research. During later authorized batches, reassess after each bounded result and publish completed reports and incremental evidence checkpoints as work proceeds.
